Abstract

The invention provides a combined material of a PU elastomer used for a vehicle foot pad and a preparation method thereof. The combined material of a PU elastomer consists of a component A and a component B, wherein, the component A consists of PPG, a chain extender, fillings, a plasticizer, a flame retardant, an age inhibitor, a catalyst and color paste; the component B is the reaction product of PPG and isocyanate. When in use, the component A and the component B are mixed according to a weight ratio that A: B is equal to 100: 30 to 65, thus being capable of manufacturing the PU elastomer used for a vehicle foot pad. The combined material of the PU elastomer used for the vehicle foot pad and the preparation method thereof have the advantages that the technique flow is simple, the periodis short, the cost value is high and the color of the product can be randomly adjusted when the product is manufactured, thus being completely capable of meeting each performance demand on the vehicle foot pad.

Description

Technical field: [0001] The invention belongs to the technical field of the preparation method of polyurethane elastomer composite material. Background technique: [0002] At present, with the rapid development of the automobile manufacturing industry, the demand for automobile floor mats is also rising rapidly, and the requirements for comfort, wear resistance, and economy are also getting higher and higher. With its superior performance, the production and application range of polyurethane materials are rapidly expanding and popularizing, and they have played an increasingly important role in various fields of the national economy. In recent years, many automobile manufacturers and parts manufacturers have higher requirements for the comfort of the floor mats, especially the appearance. The original automobile floor mats are mostly rubber products. The production of rubber products requires high pressure, cumbersome processes, and long cycles. Its color is not easy to adj...
